Intel's Core Microarchitecture, as featured in Core 2 (codenames Merom, Allendale, Conroe and Woodcrest), introduce a large number of improvements over the previous Core Solo and Core Duo (codenamed Yonah) processor range - the biggest improvement being 64-bit compatibility.


Usage In Macs

Core 2 Duo - "Merom" (64-bit, dual-core)

Core 2 Duo - "Merom - Santa Rosa based" (64-bit, dual-core)

The Santa Rosa brought a faster FSB bus to the table raising it to 800 MHz as well as many other small improvements.

Core 2 Duo - "Penryn" (64-bit, dual-core)

Penryn was an incremental update to Intel's product line. It offers slightly faster speeds while being more power efficient.

Core 2 Duo - "Penryn - Montevina based" (64-bit, dual-core)

Montevina based processors are technically yet to appear in a Mac. However, Apple's Rev. D iMac includes a custom-built Santa Rosa based processor which comes with the main benefits of Montevina such as its 1066 MHz FSB. To the average consumer, these technicalities aren't a concern if the performance is roughly equivalent to the real Montevina based processors.

The server lineup is marketed as Xeon Core and thus is not listed on this page.
